Hydrolytic enzyme and plant growth promotion activity of fungal and bacterial endophytes of tomato

Abstract

Endophytes are plant associated microorganisms that live inside plant tissues without causing any harm to plants. Studies on microorganisms from plant species are recently becoming more frequent, since these fungi and bacteria have been studied for biological control and production of compounds with pharmacological properties. An attempt was made to study the efficacy of the endophytic microorganisms isolated from tomato in showing hydrolytic enzyme and plant growth promotion activity under in vitro condition and results revealed that, among nine fungal and eight bacterial isolates, TRBBA-23, SBHKA-2 and LBDRA-5 showed positive reaction for all the tests (amylase, protease, lipase, siderophore production and phosphate solubilisation). Isolates RFBBE-19, SFDDE-12 and LFDLA-9 showed positive reaction for all the tests except for phosphate solubilisation.
